14Which is true about the sensory pathways of the spinal cord
- AThe dorsal columns are responsible for discriminative touch, vibration, and proprioception and the lateral spinothalamic tracts are responsible for pain and temperature.
- BThe dorsal columns are responsible for discriminative touch, pain, and proprioception and the lateral spinothalamic tracts are responsible for vibration and touch.
- CThe dorsal columns are responsible for pain and vibration, and the lateral spinothalamic tracts are responsible for discriminative touch, proprioception and temperature.
